[PHP + AWS SDKでAthena] getQueryResultsの結果が扱いづらいので扱いやすくする。2018-08-14

Last updated at Posted at 2018-08-14

概要

長くなるので割愛しますが、PHP + AWS SDKでAthenaの実行結果(結果例)をgetQueryResultsで取得すると少し扱いづらいです
扱いやすい形式に変換してみます

install

% composer require abetomo/convert-athena-query-results-to-array

コード例

こちらのコード例 から変更したところを抜粋して記載します

example.php
<?php
// ... これより上は省略
// 3. 結果の取得
$getQueryResultsResponse = $athenaClient->getQueryResults([
    'QueryExecutionId' => $queryExecutionId
]);

use Abetomo\ConvertAthenaQueryResultstoArray\ConvertAthenaQueryResultstoArray;
// getQueryResultsの結果を
// ConvertAthenaQueryResultstoArray::convert()
// で変換します
print_r(ConvertAthenaQueryResultstoArray::convert($getQueryResultsResponse->get('ResultSet')));

実行結果

string(36) "QueryExecutionId-XXXXX"
[waitForSucceeded] State=RUNNING
[waitForSucceeded] State=RUNNING
[waitForSucceeded] State=SUCCEEDED
Array
(
    [0] => Array
        (
            [account_id] => id1
        )

    [1] => Array
        (
            [account_id] => id2
        )

    [2] => Array
        (
            [account_id] => id3
        )

)

こちらの結果 と比較するとシンプルな配列になりました

まとめ

PHP + AWS SDKでAthenaの実行結果をシンプルな配列に変換して扱いやすくしました
